Below is a simple script to get the length of any string.
#!/bin/bash
echo "enter the sting: "
read str;
countStringLength() {
echo `echo -n $1 | wc -c`
# Or can use the below trick to get the string length
# I prefer to use the first one - easy to use and easy to remember
echo ${#1}
}
countStringLength $str
echo "enter the sting: "
read str;
countStringLength() {
echo `echo -n $1 | wc -c`
# Or can use the below trick to get the string length
# I prefer to use the first one - easy to use and easy to remember
echo ${#1}
}
countStringLength $str
